The Mayon volcano spews grayish ash for the second time in a day on Wednesday in Albay province, about 212 miles southeast of Manila, Philippines. The country's most active volcano last erupted in 2006 and typhoon-triggered mudslides later that year buried entire villages, killing more than 1,000 people.

MANILA, Philippines — The cone-shaped Mayon volcano in the central Philippines, which killed scores in an eruption 16 years ago, shot up an ash plume Wednesday — prompting hundreds of nearby residents to evacuate in case it blows again.

Chief state volcanologist Renato Solidum said the alert level remains the same at Mayon, the country's most active volcano, but that if magma continues to rise below the glowing crater there could be another eruption within weeks.

In Daraga township south of the volcano's crater, Mayor Cicero Triunfante ordered the early evacuation of more than 800 residents in the villages of Matnog and Banadero on fears that it might be in the path of superheated volcanic debris called pyroclastic flow.

Elsewhere, officials distributed wireless public address systems to more than 700 village and town officials to help them make emergency evacuation announcements if necessary, said provincial disaster officer Cedric Daep.

He said mass evacuations would be ordered once the Philippine Institute of Volcanology and Seismology raises the alert to the next higher level. About 30,000 people were evacuated when it last erupted in 2006.

Resident volcanologist Ed Laguerta said ground measurements showed that the upper slopes of Mayon were slightly inflated, indicating the presence of rising magma, and that minor ash explosions are to be expected. Hourly measurements were being taken, he added.
